Alsea River, Benton and Lincoln Counties. Alsea is a corruption of Alsi, the original name of a Yakonan tribe that lived at the mouth of Alsea River. Lewis and Clark give Ulseah. Duflot de Mofras gives Alsiias in his Exploration (1844), volume II, page 335. Lt. Wm. P. McArthur gives Alseya on his chart accompanying the report of the U. S . Coast Survey for 1851. The name has numerous variations, but there is no doubt but that it was originally pronounced with three syllables, and not with two as at present. Alsea River rises in the Coast Range and flows into Alsea Bay at Waldport. The town of Alsea is in the southwest part of Benton County. The U. S. Geographic Board has adopted the form Alsea.
